°C. Limits over temperature are guaranteed by design.

Note 2: R1 = 215k

Ω, R2 = 210kΩ for the MAX4069 only (see Functional Diagram). This sets REFOUT to 2.49V nominal.

Note 3: Guaranteed by the PSRR test.

Note 5: Input-Referred Offset Voltage is defined as the voltage difference between OUT and REFOUT, divided by the selected gain

Note 7: Total OUT Voltage Error is the sum of offset voltage and gain errors. The output voltage is measured relative to the reference

(REFOUT or REFIN).
